United States Patent 3,406,675 ARCHERY BOW WITH HANDGRIP ADJUSTING MEANS AND ARROW SUPPLY SUPPORT Bert E. Fredrickson, 1208 S. Baird St., Green Bay, Wis. 54301 Filed July 1, 1966, Ser. No. 562,182 6 Claims. (Cl. 124-24) This invention relates to an archery bow.

An object of the present invention is to provide an archery bow in which the limbs are each capable of being adjusted to thereby increase and decrease the tension of the bowstring.

Another object of the present invention is to provide an archery bow having a handgrip which is constructed and arranged so as to enable an archer to maintan an arrow about to be shot in alignment with the line of sight.

A further object of the present invention is to provide an archery bow which includes an arrow rest of such construction as to cause the nock of the arrow to be shot to engage the bowstring and hold the arrow in cocked position until shot.

A still further object of the present invention is to provide an archery bow which holds the arrow to be shot in alignment with the line of sight during the initial stage of flight.

A still further object of the present invention is to provide an archery bow wherein the arrow rest is located behind and spaced from the bow section and the front side carries an adjustable horizontally-disposed arrow point-supporting member, enabling the supporting member receiving the arrowpoint of an arrow to be shot when supported upon the arrow rest with the mock engaged by the bowstring to thereby hold the arrow in readiness for use.

Other and further objects of the present invention will become apparent from the following description taken in conjunction with the accompanying drawings, in which:

FIGURE 1 is a perspective view of an archery bow according to the present invention.

FIGURE 2 is an enlarged rear view of the assembly of FIGURE 1 with parts of the limbs broken away.

FIGURE 3 is a sectional view taken on the line 33 of FIGURE 2.

FIGURE 4 is a sectional view taken on the line 4-4 of FIGURE 3.

FIGURE 5 is a sectional view taken on the line 5--5 of FIGURE 3.

FIGURE 6 is a sectional view taken on the line 6-6 of FIGURE 5.

FIGURE 7 is a sectional view taken on the line 77 of FIGURE 3.

Referring to the drawings, the numeral 10 designates generally the archery bow according to the present invention, the archery bow comprising an upstanding bow section 12 provided with an opening 14 through which arrows are adapted to be shot. A first socket 16 projects from and opens out of the upper end of the bow section 12, and a hollow handle 18 projects from the lower end of the bow section 12. Depending from and opening out of the handle 18 is a second socket 20. A first limb 22 has a portion adjacent one end which is mounted in the first socket 16, and a second limb 24 has 1 portion adjacent one end which is mounted in the second socket 20, a bowstring 26 being stretched between and attached to the other ends of the first and second limbs 22 and 24.

As will be observed from FIGURE 3, each of the first and second sockets 16 and 20, flares inwardly from the open end thereof, and each of the one end portions of the first and second limbs 22 and 24 is shaped to a tapered configuration.

Independent means connects each of the first and sec- Cil 3,406,675 Patented Oct. 22, 1968 0nd limbs 22 and 24 to the first and second sockets 16 and 20 for limited forward and backward rocking movement of the first and second limbs 22 and 24 relative to the bowstring 26 to thereby increase and decrease the tension of the bowstring 26. Specifically, this means comprises opposed nubs 28, FIGURE 3, which are inwardly of and contiguous to the open end of each of the first and second sockets 16 and 20, and opposed elements 30 and 31 are adjustably-supported in the wall of each of the first and second sockets 16 and 20, the opposed elements 30 and 31 being a threaded pin and a headed bolt having a threaded shank, respectively. The nubs 28 and the opposed elements 30 and 31 of the first and Second sockets 16 and 20 engage the tapered one end portion of the first and second limbs 22 and 24, adjustment of the opposed elements or threaded pin and headed bolt with the threaded shank effecting limited forward and backward rocking movement of the first and second limbs 22 and 24 relative to the bowstring 26 to thereby increase and decrease the tension of the bowstring. The independent means also includes opposed releasable fastening members 32 which are adjustably-carried by the wall of each of the first and second sockets 16 and 20, these fastening elements being set screws and contacting the tapered end portions of the first and second limbs 22 and 24 to thereby retain the first and second limbs 22 and 24 in the adjusted positions.

A handgrip 34 is circumposed about the handle 18, and means connects the grip 34 to the handle 18 for limited rotational movement of the grip in clockwise and counterclockwise directions to thereby maintain an arrow about to be shot from the bow section 12 in alignment with the line of sight. Specifically, this means embodies, FIG- URES 5 and 6, a ball-and-socket joint 36 which is disposed transversely of and is carried by the handle 18 intermediate its ends thereof, and is secured to the handgrip 34 by means of the ends of a rivet 34 which are flattened to thereby secure the rivet 34 to the handgrip 34. It is to be noted that the handle 18 is provided with slots 18' which receive the projecting end portions of the rivet 34, the slots serving to permit the limited clockwise and counterclockwise movement of the handgrip 34.

A rear sight 40 is disposed a short distance behind the rear face of the bow section 12 and within the area defined by the opening 14 of the bow section 12, the rear sight comprising a horizontal support bar 41 which is behind and adjacent the opening 14 of the bow section 12 and extends transversely of the opening 14, and is attached to the complemental rear ends of a pair of laterally-spaced elongated support members 42, the support members 42 extending into and through the bow section 12 and attached to the sides of the bow section as by bolts 43, as clearly shown in FIGURE 4. At rear sight member 44 is adjustably-supported in an elongated slot 45 formed in the horizontal support bar 41. The rear sight member 44 is in the form of a ring which is fixedly-attached to the upper end of a bolt-and-nut assembly 46 adjustablymovable along the slot 45.

As shown in FIGURES 1 and 3, the support members 42 project out of and beyond the front face of the bow section 12 and the complemental forward ends of the support members 42 are received in and are fixedlysecured to a front side 50. Specifically, the front side 50 consists of a frame 51 having a base piece 52, a pair of side pieces 53 rising from the base piece, and a top piece 54 extending across and secured to the upper ends of the side pieces 53, Upon inspection of FIGURE 1 it will be seen that the complemental forward ends of the support members 42 are received in and are fixedly-secured to the side pieces 53. A front side member 55 is adjustablysupported in an elongated slot 56 formed in the top piece 3 54. The front side member 55 is in the form of a ball which is fixedly-attached to the upper end of a bolt-andnut assembly 57 adjustably-movable along the slot 56.

The horizontal support bar 41 of the rear sight 40, FIGURE 2, is provided with a pair of up upstanding clamps 60 which are disposed on opposite sides of the front side member 55. A pair of vertically-spaced clamps 62 project from the inner face of each of the support members 42 inwardly of and adjacent the complemental rear ends. The base piece 52 of the frame 51 of the front side 50, FIGURE 1, is provided with a horizontally-disposed supporting member 64 which projects from the inner face of the base piece 52 and which is adjustably-carried by the base piece 52. Specifically, the supporting member 64 is in the form of an externally-threaded sleeve which is adjustably-supported in the base piece 52. A pair of vertically spaced circular apertures 66 are formed in each of the side pieces 53 of the frame 51 of the front side 50, and a pair of laterally-spaced circular apertures 67 are formed in the base piece 52 of the frame 51 of the front side 50. The clamps 60 and 62 and the apertures 66 and 67 which are complemental thereto support the shafts of arrows 80 inwardly of the nooks and the arrow points 81 of the arrows, as shown in dotted lines in FIGURE 2. The purpose of the supporting members 64 will be subsequently described.

.An arrow rest 70 is located behind and spaced from the opening 14 of the bow section 12. In actuality, the rest 70 is located below and behind the rear sight 40 and faces toward the opening 14 of the bow section 12. The arrow rest 70, FIGURES 2, and 7, comprises a base 71, side members 72 rising from the ends of the base, a stand 73 rising from the mid-portion of the base 71, and a wing 74 extending outwardly from the upper end of one of the side members 72, the wing 74 being fixedly-secured by means of bolts 74 to a bracket 75 fixedly-attached to the adjacent side of the bow section 12. A rest element 76 is adjustably-supported in the top of the stand 73. Mounted in the side member 72 and in cooperative relation with the rest 76 are opposed spring-biased pins 77, the pins 77 being above and partially overlying the rest element 76. The pins 77 are operable, upon application of a depressive force applied to an arrow 80 to be shot when lying thereupon, to be compressed and permit the arrow to be shifted therebetween and be supported upon the rest element 76 and be engaged by the pins 77, as shown in FIGURE 7, to thereby cause the nock of the arrow to be shot to engage the bowstring 26 and hold it in cocked position until shot, as shown in full lines in FIGURE 1.

A magnetic means is supported in the arrow rest 70 and anchored in the bow section 12 and is located forwardly of the stand 73 of the arrow rest 70. The magnetic means embodies a magnetized metal bar 78 which extends longitudinally through and beyond the opening 14 in the bow section 12 to a point adjacent to and inwardly of the front side 50 to thereby magnetically attract the metal arrow point 81 of an arrow 80 to be shot when supported upon the rest element 76 and engaged by the pins 77 to hold the arrow 80 in alignment with the line of sight during the initial stage of flight, as shown in FIG- URES 1, 3 and 4. The bar 78 is attached to the stand 73 of the arrow rest 70 by means of a screw 79, and is anchored to the base of the bow section 12 by means of a threaded bolt 82 which is supported in an ear 83 depending from the bar 78 and which is in threaded engagement with the base of the bow section 12.

In operation, the archer grasps one of the arrows 80 and removes its shaft from the adjacent clamp 62, and then pulls the shaft backwardly to free the arrow point 81 from seating engagement in the hole 69, whereupon he inserts the arrow point 81 in the supporting member 64, and then places the shaft inwardly of the nock so that it lies upon the opposed pins 77. At this point the archer applies a depressive force upon the shaft of the arrow 80 as it lies upon the pins 77, causing the pins 77 to be compressed and permit the shaft of the arrow to be supported upon the rest element 76 and be engaged by the pins 77, followed by attaching the nock 85 to the bowstring 26 slightly below the knot 86 formed in the bowstring 26, as shown in dotted lines in FIGURE 1. Next, the archer, in turn, withdraws the arrow point 81 from the supporting member 64, raises the nock 85 to a point contiguous to the knot 86, shifts the arrow 80 so that it extends in parallelism with'the magnetized bar 78, pulls the cocked arrow backwardly until the arrow point 81 is opposite the inner end of the magnetized bar 78, and releases the arrow. As the arrow 80 is released the-metal arrow point 81 is attracted to and guided along the magnetized bar 78.
